This study examined the relative contributions of phonological awareness, orthographic pattern recognition, and rapid letter naming to fluent word and connected-text reading within a dyslexic sample of 123 children in second and third grades. Participants were assessed on a variety of fluency measures and reading subskills. Correlations and hierarchical multiple regression analyses were carried out to explore these relationships. The results demonstrate that phonological awareness, rapid letter naming, and orthographic pattern recognition contribute to word-reading skills. Furthermore, rapid naming, orthographic pattern recognition, and word reading fluency moderately predict different dimensions of connected-text reading (i.e., rate, accuracy, and comprehension) whereas phonological awareness contributes only to the comprehension dimension of connected-text reading. The findings support the multidimensional nature of fluency in which the whole is more than its parts.  相似文献

This study explores the contribution of cognitive processes to comprehension skills in adults who suffered from childhood developmental dyslexia (CD). The performance of adults with CD (ages 17 to 23), chronological age-matched (CA) adults, and reading level-matched (RL) children was compared on measures of phonological processing, naming speed, working memory (WM), general knowledge, vocabulary, and comprehension. The results showed that adults with CD scored lower on measures of phonological processing, naming speed, WM, general knowledge, and vocabulary when compared to CA readers but were comparable to RL children on the majority of process measures. Phonological processing, naming speed, vocabulary, general knowledge, and listening comprehension contributed independent variance to reading comprehension accuracy, whereas WM, intelligence, phonological processing, and listening comprehension contributed independent variance to comprehension fluency. Adults with CD scored lower than CA adults and higher than RL children on measures of lexical processing, WM, and listening comprehension when word recognition and intelligence were partialed from the analysis. In summary, constraints in phonological processing and naming speed mediate only some of the influence of high-order processes on reading comprehension. Furthermore, adults with CD experience difficulties in WM, listening comprehension, and vocabulary independently of their word recognition problems and intellectual ability.  相似文献

The present study investigated proximal and distal predictors of reading comprehension by including latent factors such as alphabet knowledge, phonological awareness, semantic knowledge, word reading, oral reading fluency, and reading comprehension. The sample consisted of 79 five-year-old Korean-monolingual children who were assessed at the end of the school year. The results showed that alphabet knowledge, phonological awareness, and semantic knowledge latent variables were all positively and highly related to word-reading skills, but phonological awareness made a unique contribution above and beyond alphabet knowledge and semantic knowledge. Word reading was highly related to oral reading fluency and directly related to reading comprehension. Oral reading fluency, although a separate construct from word reading accuracy, was not uniquely related to reading comprehension after accounting for the effects of word reading and semantic knowledge. Semantic knowledge was fairly strongly and uniquely related to reading comprehension.  相似文献

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework.  相似文献

The lexical decision (LD) and naming (NAM) tasks are ubiquitous paradigms that employ printed word identification. They are major tools for investigating how factors like morphology, semantic information, lexical neighborhood and others affect identification. Although use of the tasks is widespread, there has been little research into how performance in LD or NAM relates to reading ability, a deficiency that limits the translation of research with these tasks to the understanding of individual differences in reading. The present research was designed to provide a link from LD and NAM to the specific variables that characterize reading ability (e.g., decoding, sight word recognition, fluency, vocabulary, and comprehension) as well as to important reading-related abilities (phonological awareness and rapid naming). We studied 99 adults with a wide range of reading abilities. LD and NAM strongly predicted individual differences in word identification, less strongly predicted vocabulary size and did not predict comprehension. Fluency was predicted but with differences that depended on the way fluency was defined. Finally, although the tasks did not predict individual differences in rapid naming or phonological awareness, the failures nevertheless assisted in understanding the cognitive mechanisms behind these reading-related abilities. The results demonstrate that LD and NAM are important tools for the study of individual differences in reading.  相似文献

We examined the developmental relationships between home literacy environment (parent teaching, shared book reading) and emergent literacy skills (phonological awareness, letter knowledge, vocabulary, rapid naming speed) in kindergarten, reading accuracy and fluency in Grade 1, and reading comprehension in Grades 2 and 3 in a sample of Canadian children learning to read English (N = 214). Results from a latent variable model showed that parent teaching predicted letter knowledge and phonological awareness, and shared book reading predicted vocabulary and rapid naming speed after controlling for family socioeconomic status. Moreover, both parent teaching and shared book reading contributed indirectly to reading accuracy and fluency in Grade 1, which then mediated the effects of home literacy environment on reading comprehension in Grades 2 and 3. The results suggest that the effects of home literacy environment on later reading development are distributed via more pathways than previously thought.  相似文献

The purpose of this study was to compare the contribution of two different versions of working memory to word reading and reading comprehension in relation to phonological awareness and rapid naming speed. Fifty children were administered two measures of working memory, namely an adaptation of the Daneman and Carpenter sentence span task and Sentence Question, tests of phonological awareness, rapid naming speed, word reading and reading comprehension. The results indicated that Sentence Question accounted for unique variance over and beyond the effects of Daneman and Carpenter's sentence span task, whereas the latter did not when the effects of Sentence Question were partialled out. In addition, both phonological awareness and rapid naming were accounting for unique variance beyond the effects of working memory in predicting reading. The role of working memory on reading is discussed, and future directions for research are suggested.  相似文献

Arabic native speaking children are born into a unique linguistic context called diglossia (Ferguson, word, 14, 47–56, [1959]). In this context, children grow up speaking a Spoken Arabic Vernacular (SAV), which is an exclusively spoken language, but later learn to read another linguistically related form, Modern Standard Arabic (MSA). Forty-two first-grade Arabic native speaking children were given five measures of basic reading processes: two cognitive (rapid automatized naming and short-term working memory), two phonological (phoneme discrimination and phoneme isolation), and one orthographic (letter recoding speed). In addition, the study produced independent measures of phonological processing for MSA phonemes (phonemes that are not within the spoken vernacular of children) and SAV phonemes (phonemes that are familiar to children from their oral vernacular). The relevance of these skills to MSA pseudoword reading fluency (words correct per minute) in vowelized Arabic was tested. The results showed that all predictor measures, except phoneme discrimination, correlated with pseudoword reading fluency. Although phonological processing (phoneme isolation and discrimination) for MSA phonemes was more challenging than that for SAV phonemes, phonological skills were not found to affect reading fluency directly. Stepwise regression analysis showed that the strongest predictor of reading fluency in vowelized Arabic was letter recoding speed. Letter recoding speed was predicted by memory, rapid naming, and phoneme isolation. The results are discussed in light of Arabic diglossia and the shallow orthography of vowelized Arabic.  相似文献

This study focuses on the shared variance between reading comprehension and word-level reading skills in a population of 534 Greek children in Grades 2 through 4. The correlations between measures of word and pseudoword accuracy and fluency, on the one hand, and vocabulary and comprehension skills, on the other, were sizeable and stable or increasing with grade. However, the unique contribution of word reading to comprehension became negligible after vocabulary measures were entered in hierarchical regression analyses, particularly for higher grades, suggesting that any effects of decoding on comprehension may be mediated by the lexicon, consistent with lexical quality hypothesis. Structural modeling with latent variables revealed an invariant path across grades in which vocabulary was defined by its covariation with reading accuracy and fluency and affected comprehension directly. It is argued that skilled word reading influences comprehension by strengthening lexical representations, at least when phonological decoding can be relatively effortless.  相似文献

This study investigated the adequacy of an expanded simple view of reading (SVR) framework for English language learners (ELLs), using mediation modeling approach. The proposed expanded SVR included reading fluency as an outcome and phonological awareness and naming speed as predictors. To test the fit of the proposed mediation model, longitudinal data from 308 ELLs from different linguistic backgrounds were analyzed using structural equation modeling. We examined the mediating role of Grade 2 word-level reading skills in the association between Grade 1 phonological awareness, naming speed, and listening comprehension and Grade 3 reading comprehension and reading fluency. The results indicated that word-level reading skills fully mediated the association between phonological awareness, reading comprehension and reading fluency. Word-level reading skills partially mediated the association between naming speed and reading fluency. Listening comprehension contributed directly to reading comprehension and reading fluency. It appears that reading development in ELLs is better understood when reading fluency is added to the SVR framework as an outcome and naming speed as a building block of SVR. Theoretical aspects of the mediation model in relation to ELL reading development are also addressed.  相似文献

A sample of 169 German children were tested in general verbal ability, verbal memory span, phonological awareness, lexical access speed and accuracy, and letter knowledge in preschool. These tests were used as independent measures predicting performance on second grade reading comprehension, word discrimination, and word decoding speed. Tests of verbal ability, memory capacity, and phonological awareness were also given over a year later in elementary school. After determining that the influence of verbal ability, memory capacity, and phonological awareness on reading comprehension was comparable when measured in preschool and elementary school, the effects of all preschool measures on the three dependent reading measures were assessed. These analyses revealed differential main effects and interactions for the three dependent measures. However, a significant three-way interaction among lexical access, memory capacity, and phonological awareness was found for all three reading measures. These results indicate that the interaction and subsequent effects of these linguistic skills precedes and influences reading acquisition. This is contrary to the view that these skills interact as a result of reading experience. The implications of these results, as well as comparisons of conducting such studies with German rather than English speaking children are discussed.  相似文献

Two experiments and three measures of lexical skills (word finding, rapid automatized naming, receptive vocabulary) were administered to 24 third and 24 fifth graders. Each experiment included two between-subject variables (grade and sex) and four within-subject variables (mode of sentence presentation – one word and one-sentence-at-a-time; word type – orthographic, phonological and semantic foils; position of foil in sentence – beginning, middle, and end; and sentence type – meaningful and nonsense). The experiments contrasted on reading comprehension task: receptive sentence acceptability (Experiment 1) or expressive sentence reproduction (Experiment 2). One-word-at-a-time presentation, which highlights the lexical unit, resulted in better accuracy on the expressive task that required verbatim reproduction than on the forced choice receptive task. Word finding and rapid automatized naming that require active production of phonologically-referenced name codes, but not receptive vocabulary, were correlated with measures of word recognition and reading comprehension in the experiments and on the psychometric tests. These results are consistent with Perfetti's contention that a phonologically-based name code is the heart of lexical access.  相似文献

This study examines (a) how rapid automatized naming (RAN) speed components—articulation time and pause time—predict reading accuracy and reading fluency in Grades 2 and 3, and (b) how RAN components are related to measures of phonological awareness, orthographic knowledge, and speed of processing. Forty-eight children were administered RAN tasks in Grades 1, 2, and 3. Results indicated that pause time was highly correlated with both reading accuracy and reading fluency measures and shared more of its predictive variance with orthographic knowledge than with phonological awareness or speed of processing. In contrast, articulation time was only weakly correlated with the reading measures and was rather independent from any processing skill at any point of measurement.  相似文献

The present study examined the relationship of phonological awareness, naming speed, and verbal memory to the scores obtained from five tests assessing word attack, word identification, reading comprehension, and spelling skills in 54 children with severe reading disabilities (48 boys and 6 girls; M age = 9 years, 7 months). Multiple regression analyses indicated that the best predictor of achievement across the five academic tests was the Verbal Comprehension factor from the Wechsler Intelligence Scale for Children-Revised. Age, socioeconomic status (SES), and externalizing behavior problems were also significant predictors of achievement, depending on the academic measure. After controlling for age, SES, behavior problems, and intelligence, the phonological awareness task added significantly to the prediction of word attack, spelling, and reading comprehension scores; rapid letter naming added significantly to the prediction of word identification and prose passage speed and accuracy scores; and a word-list memory task added significantly to the prediction of word recognition scores. These results suggest that several independent processes interact to determine the extent and severity of reading problems.  相似文献

The present study investigated the associations of visual-spatial attention with word reading fluency and spelling in 92 third grade Hong Kong Chinese children. Word reading fluency was measured with a timed reading task whereas spelling was measured with a dictation task. Results showed that visual-spatial attention was a unique predictor of speeded reading accuracy (i.e., the total number of words read correctly divided by the total number of words read in a timed reading task) but not reading speed (i.e., the number of words read correctly in the same task) after controlling for age, non-verbal intelligence, morphological awareness, phonological awareness, orthographic knowledge, and rapid automatized naming. Visual-spatial attention also explained unique variance in word spelling measured with a dictation task after the same control variables. The findings of the present study suggest that visual-spatial attention is important for literacy development in Chinese children.  相似文献

In the present study we examined the relation between alphabet knowledge fluency (letter names and sounds) and letter writing automaticity, and unique relations of letter writing automaticity and semantic knowledge (i.e., vocabulary) to word reading and spelling over and above code-related skills such as phonological awareness and alphabet knowledge. These questions were addressed using data from 242 English-speaking kindergartners and employing structural equation modeling. Results showed letter writing automaticity was moderately related to and a separate construct from alphabet knowledge fluency, and marginally (p = .06) related to spelling after accounting for phonological awareness, alphabet knowledge fluency, and vocabulary. Furthermore, vocabulary was positively and uniquely related to word reading and spelling after accounting for phonological awareness, alphabet knowledge fluency, and letter writing automaticity.  相似文献

Because of the research demonstrating the roles of phonological awareness, serial naming speed, and orthographic processing in reading, a test of each of these skills was added to a preschool screening battery. The main aim of the study was to determine whether these measures would contribute to the prediction of reading. The 118 subjects were first tested six months before kindergarten entry and were followed up 19 and 24 months later. Each additional screening test made a significant, independent contribution to the prediction of early first grade word reading/spelling, after the contributions of a parent rating of preschool reading ability (PRA), verbal IQ, socio-economic status (SES), and chronological age were accounted for. With letter naming and PRA, the additional tests were responsible for 62 percent of the variance. The orthographic test made the largest single contribution (32%) to the variance in word reading/spelling. Variables contributing significantly to the prediction of later first grade reading comprehension were (in order of proportion of the variance accounted for) letter naming, sentence memory, object naming speed, the orthographic test, and SES. The revised preschool screening battery correctly identified 91 percent of individual first grade good and poor readers. It was concluded that preschool measures of phonological awareness, serial naming speed, and orthographic processing make a strong contribution to prediction of first grade reading.  相似文献

This study examines the core predictors of the covariance in reading and arithmetic fluency and the domain-general cognitive skills that explain the core predictors and covariance. Seven-year-old Finnish children (N = 200) were assessed on rapid automatized naming (RAN), phonological awareness, letter knowledge, verbal counting, number writing, number comparison, memory skills, and processing and articulation speed in the spring of Grade 1 and on reading and arithmetic fluency in the fall of Grade 2. RAN and verbal counting were strongly associated, and a constructed latent factor, serial retrieval fluency (SRF), was the strongest unique predictor of the shared variance. Other unique predictors were phonological awareness, number comparison, and processing speed. Findings highlight the importance of SRF in clarifying the relation between reading and arithmetic fluency.  相似文献

Many studies have shown that learning to read in a second language (L2) is similar, in many ways, to learning to read in a first language (L1). Nevertheless, reading development also relies upon oral language proficiency and is greatly influenced by orthographic consistency. This longitudinal study aimed to analyze the role of linguistic predictors (phonological awareness, letter knowledge, pseudoword repetition, morphosyntactic comprehension, lexical knowledge and rapid naming) in reading outcomes (fluency, accuracy and comprehension) in a group of bilingual children (n = 30) reading Italian as an L2, compared to a group of monolingual children (n = 56). We ran a multi-group structural equation model. Our findings showed that rapid automatized naming was a significant predictor of reading speed in both groups. However, the study revealed different patterns of predictors for reading accuracy, predictors for monolinguals being LK, phonological awareness and lexical knowledge, while pseudoword repetition was a predictor for bilinguals. Morphosyntactic comprehension was the most significant predictor of comprehension skills in bilingual children. Implications for clinical and educational settings are discussed.  相似文献

This study examined differences between adequate and poor readers in phonemic awareness, rapid continuous and confrontation naming, and visual symbol processing. It also investigated which of these skills make independent contributions to word recognition, pseudoword reading, and reading comprehension. Subjects were 170 school referrals of average intelligence, aged 6 to 10 years. The strongest differentiators of adequate and poor readers, with IQ and reading experience controlled, were phonemic awareness, naming speed for letters and pictured objects, and visual symbol processing. Letter naming speed made the largest independent contribution to word recognition, phonemic awareness to pseudoword reading, and object naming speed to reading comprehension. Confrontation picture naming accounted for minimal variance in reading skills, when IQ was controlled. It was concluded that tasks of naming speed, phonemic awareness, and visual symbol processing are valuable components of a diagnostic battery when testing children with possible reading disability.  相似文献
